摘要： The invention shows how powder injection molding may be used to form a continuous body having multiple parts, each of which has different functional properties such as corrosion resistance or hardness, there being no connective materials such as solder or glue between the parts. This is accomplished through careful control of the relative shrinkage rates of these various parts. Although there is no limit to how many parts with different functional properties can make up an object, special attention is paid to certain pairs of functional properties that are difficult and/or expensive to combine in a single object when other manufacturing means are used.
摘要翻译：本发明示出了如何使用粉末注射成型来形成具有多个部分的连续体，每个部分具有不同的功能性质如耐腐蚀性或硬度，在部件之间不存在诸如焊料或粘合剂的连接材料。这是通过仔细控制这些各个部件的相对收缩率来实现的。尽管对于具有不同功能性质的多个部件可以组成一个对象没有限制，但是特别注意在使用其它制造装置时在单个对象中组合的某些功能特性对很困难和/或昂贵。

摘要： The invention shows how powder injection molding may be used to form a continuous body having multiple parts, each of which has different physical properties such as magnetic characteristics or hardness. This is accomplished through careful control of the relative shrinkage rates of these various parts. Additionally, care is taken to ensure that only certain selected physical properties are allowed to differ between the parts while others may be altered through relatively small changes in the composition of the feedstocks used. An additional application of the present invention is a process for forming, in a single integrated operation, an object that is contained within an enclosure while not being attached to said enclosure. This is accomplished by causing the shrinkage rate of the object to be substantially greater than that of the enclosure. As a result, after sintering, the object is found to have detached itself from the enclosure and is free to move around therein. Several examples of structures formed using these processes are presented.
